The physics behind baseball essay

Andrew Griesmer July 17, Professional baseball pitchers are able to make a baseball move left, right, down, and even up sort of to get it by the opposing batter. The physics behind this can be explained by the Magnus effect. Gravity pulls the ball downwards, drag slows the ball down, and the Magnus force… Well, that depends on the pitch. As the ball spins in its flight path, pressure variations form on it and the Magnus effect generates a force perpendicular to the motion of the ball in the direction of the spin.

This presents the results of a field study sponsored by the Amateur Softball Association. The data show that the swing speed of a typical player is inversely related to the bat moment of inertia about the handle with a fixed bat weight and nearly independent of the weight of the bat at fixed moment of inertia.

Russell, and Lloyd V. Smith, The Engineering of Sport V, eds. Toy model for the trampoline effect. This paper presents a simple physical picture of the "trampoline effect" in hollow bats and demonstrates how the effect leads to a larger coefficient of restitution.

A special section presents new data showing there is no measureable trampoline effect with a corked bat.

Analysis of Knuckleball TrajectoriesAlan M. Nathan, Procedia Engineering 34, The data reveal that, contrary to popolar belief, knuckleball trajectories are as smooth as those from normal pitches. However, the data also show that the deflection of a knuckleball from a straight-line trajectory is essentially random in both magnitude and direction.

Spin of a Batted BaseballAlan M. Experiments are conducted to investigate the spin of a baseball undergoing an oblique collision with a bat. A baseball was fired horizontally at speeds up to mph onto a 3"-diameter cylinder of wood that was rigidly attached to a wall.

In one experiment, a two-wheel pitching machine was used in which the backspin or topspin of the incident ball coold be adjusted.

In another experiment, an air cannon was used to project the ball with no spin.

In both experiments, markers on the ball were tracked with high-speed video to determine the velocity and spin vectors, before and after the scattering. Our primary results are as follows: Implications for the spin of batted baseballs are explored.

Dependence of fly ball distance on vertical launch angle for balls hit in the velocity range shown in the legend. These are data from actual MLB games in which the TrackMan Doppler radar system was used to measure the fly ball trajectory. The trajectory of a baseball moving through the air is very different from the one we teach in our introductory classes, in which the only force is that due to gravity.

In reality, the aerodynamic drag force which retards the motion and the Magnus force on a spinning baseball which causes the ball to curve play very important roles that are crucial to many of the subtleties of the game.

Despite their importance, our knowledge of how these forces affect the flight of the baseball has been qualitative at best. Recently, however, new tools have been developed for measuring accurate baseball trajectories during an actual game.

In this article, I will discuss these new tools and give some examples of what they are teaching us about the game of baseball.Join our friend Dr. Baseball, for some short videos briefly explaining the physics behind baseball. Physics of Baseball Activities This is a collection of basic activities and experiments to help you understand the physics of baseball.

They require almost no special equipment and very little math. Other Resources We have some odds and ends in here. Baseball Links Some of our favorite places for physics and . The Physics Behind Baseball Pitches Andrew Griesmer July 17, Professional baseball pitchers are able to make a baseball move left, right, down, and even up (sort of) to get it by the opposing batter.

The physics of baseball, in general, is a very interesting subject, and the physics of hitting a baseball, in particular, is a very involved area of study that calls upon a large amount of physics and engineering, especially when it comes to bat design, and the material used .

If you hit a baseball anywhere but at the bat’s so-called sweet spot, you feel all those vibrations in your hands, and about 10 swings laters you’ll have a bruise. Baseball is a game of physics and skill. All positions have a science behind them such as pitching, batting, and playing third base.

All positions have a science behind them such as pitching, batting, and playing third base. Here you will find the answers to these questions.


I will discuss a brief history of baseball, forces that are applied in baseball, the curve ball, and what exactly happens when the ball meets the bat. Image Source: Last modified: November 27, Physics
